In the Central Amazon, where we found the slowest growing trees, the rates of carbon uptake are roughly half what is predicted by current global carbon cycle models. As a result, those models—which are used by scientists to understand how carbon flows through the Earth system—may be overestimating the forests' capacity to remove carbon dioxide from the atmosphere.
